Final answer:
The kilovolt-amperes (KVA) supplied by an APU varies by its design, typically ranging from 30 to 100 KVA in commercial aircraft. Exact specifications depend on the aircraft model.
Step-by-step explanation:
The amount of kilovolt-amperes (KVA) supplied by an Auxiliary Power Unit (APU) can vary depending on the design and purpose of the APU. An APU is an onboard generator used in aircraft to power up systems while the main engines are shut down, typically providing between 30 to 100 KVA in commercial airplanes. However, for specific models, the KVA rating could be different, and it is crucial to refer to the aircraft's technical specifications for accurate figures.
